Presentation transcript:

Name: _______________________ Nora has a battery, a light bulb, and three pieces of wire. She wants to see how many pieces of wire she needs to use to make the bulb light up. Make a prediction: what is the smallest number of wires she must to get the bulb to light up? 0 wires 1 wire 2 wires 3 wires 4 wires Now, get your bulb to light up using the MINIMUM amount of materials provided. 2. Explain how you made your bulb light up. ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ 3. Draw your design below.

Now, get your bulb to light up using a DIFFERENT way than the one you found before. 4. Explain how you made your bulb light up. ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ 5. Draw your design below. Finally, find one way that WILL NOT allow the bulb to light up. 6. Explain why you think the bulb does not light up this time. ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ 7. Draw your design below.
